Threat ImpactUnknown

Number of Occurrences81 to >300

Rank Reasons

Widely distributed across much of Canada and northern U.S. in a variety of still and moving waters, including acidic waters.

Range Extent Comments

Atlantic, Hudson Bay, Great Lakes, and Mississippi River basins in northern U.S. and southern Canada, from the Atlantic coast to southern Northwest Territories, eastern British Columbia, and Montana; south to New York, Wisconsin, and Iowa; isolated population in the upper Missouri river basin, South Dakota, Nebraska, and Wyoming (Page and Burr 2011).

Occurrences Comments

Hundreds, if not thousands of occurrences. For example, Becker (1983) mapped more than 200 collection sites in Wisconsin.

Threat Impact Comments

Localized threats may exist, but on a range-wide scale no major threats are known.

Ecology & Habitat

Habitat

Habitat includes "cCool, clear headwater streams in the south, bog drainage streams, ponds and small lakes in the north, and in stained, peaty waters of beaver ponds" (Scott and Crossman 1973). Usually these fishes occur over sand or gravel (Page and Burr 1991). Spawning occurs in clear water over sand or gravel in weak or moderate current (Scott and Crossman 1973).

Reproduction

Spawns in spring. Sexually mature at age II (Becker 1983).
